5 - "MODIFICATION" MODE
This mode allows you to change the values of all the variables
displayed on the active screen. It uses the 4 keys "1", "2", "3"
and "4" by attributing preset functions to them :
KEY / ASSOCIATED ICON
(By pressing successively on the key the cursor will move
from digit to digit, from right to left, then the cursor remains on
the last digit of the value to be changed.)
Through "MODIFICATION" mode, the user is able to :
- choose the number of the controller he wishes to see
the variables of (if several LENNOX Rooftops are
attached to the same KP07 display unit),
- control the setpoints.
To exit "MODIFICATION" mode and return to the active screen,
press the "MODIFICATION" key.
Note :
- During modification, the screen is no longer updated.
- If a change is not confirmed, the variable will retain its
previous value.
CONTRAST SETTING
The display contrast can be set in "MODIFICATION" mode :
- Pressing successively on key [A] increases the contrast.
- Pressing successively on key [B] decreases the
